Use hooks and resolvers instead of direct database calls

[HexaField]

• all feathers classes should have no overrides
• all calls to _find, _get, _create, _patch, _update, _remove are replaced with hooks
• hooks only modify parameters & queries, and handle side effects (eg. file manipulations)
• code paths are split up into multiple actions & relevant hooks
• all hooks are tested
